Hello Sir/Madam,
Hope you are doing well!!
in international transactions, transactions from joint bank account generally not recommended, receiver bank asking for KYC of sender and make both the account holder as party of the transaction, in one of our case our client sell his shares to a London base person and the london base person want to transfer the amount from his joint account then transaciton stucked in banking mechanism for around 15 days for seeking clarification.
thus as per my view if you have a seperate bank account then its recommended to transfer amount to individual saving account then to the seller of the property.
for TDS yes we have to apply for TAN and then file TDS return and thereafter surrender the TAN.
othereise seller can provide you nil TDS deduction certificate for non deduction of TAX.
